Genus Panesthia, Serv. 



Panesthia quinquedentata^ sp. n. 



Long. Corp. (^ 19-25 millim. ; ? 25-34 millim. 



Apterous, deep black ; the labrum and more or less of the 

 under surface and legs in the male varying from rufo- 

 testaceous to dark red ; the female much less marked with 

 red, and sometimes almost entirely black ; pronotum with 

 the front edge slightly raised in the female, leaving the head 

 just visible, but scarcely at all in the male ; it is slightly 

 concave only in the largest female, in which specimen alone 

 the usual two tubercles (large and wide apart) are visible in 

 front of the raised part of the pronotum. The division 

 between the lower front and the higher back portions of the 

 pronotum is less slightly marked than usual. The front is 

 depressed in the middle behind the ridge, and more coarsely 

 punctured than on the sides of the thoracic segments^ where 

 the punctuation is extremely fine. The punctuation on the 

 abdomen is slight, the punctures only becoming large and 

 numerous towards the extremity and on the terminal plate. 

 Terminal plate with five large teeth, two just behind the 

 black cerci and three terminal. Front femora unarmed. 



Hab. Nilgiris. 



Probably allied to P. ferrv(jim'pes, Brunn., but in that 

 species the terminal plate of the abdomen is described as 

 ' multi-crenulata.'" There are also a number of immature 

 specimens, perhaps belonging to P. quinquedentata, judgi ig 

 by the structure of the abdomen, but they show no trace of the 

 peculiar structure of the thorax. They are black, with more 

 or less of the borders of the thoracic segments, the legs and 

 under surface ferruginous. It is curious that most of these 

 immature specimens are males, whereas the contrary is the 

 case in the adult specimens. 



Panesthia javanica^ Serv. 



The best series of this species at present in the Museum is 

 from a doubtful locality (probably Burma), including four 

 specimens of the male, a female, and a number of larvae. 

 The males exhiljit a very interesting series of progressive 

 development, varying in size from 34-47 millim., while the 

 pronotum is scarcely more developed in the smaller specimens 

 than in the female, while in the largest it is provided with 

 very large horns, incurved and pointed at the tips. The 

 larvse agree with Penang specimens in having the red spots 

 much larger than in typical P.javanica^ and those of the
